The ultra thinwall substrate provides a larger geometric surface area, allowing more exhaust gas to interact with catalyst and leading to improved emissions performance. Tenneco Automotive's "force-closing" manufacturing process provides design flexibility to accommodate different substrate shapes and maintains uniform mounting pressure around the substrate, resulting in enhanced component and system performance.

"The shoebox design of the Ultra Thinwall Substrate Catalytic Converter used on the Jaguar models offers OEM engineers a number of significant advantages over traditional emission control technologies," said Brent Bauer, senior vice president and general manager, original equipment emission control. "These converters offer maximum design and performance flexibility, and the sensors can easily be located between different substrates to monitor emissions levels and meet OBDII requirements."

Tenneco Automotive provides automakers with a wide range of converter designs, from conventional "clamshell converters" to the advanced Ultra Thinwall Substrate Catalytic Converters. This advanced engineering and manufacturing capability allows the company to offer OEM customers the precise emissions control technology they need for specific vehicle applications.

The Ultra Thinwall Substrate Catalytic Converters are manufactured at the Tenneco Automotive facility in Ligonier, Indiana.
